With the continuous development of science and technology and human beings, people's pursuit and improvement of life, and industry's continuous demand for product quality, zirconia ceramics are more widely used in modern industry and life. Now, let us briefly introduce its main application areas.
1. 3C electronic fields such as mobile phones
Zirconia ceramics are widely used in 3C electronic fields such as mobile phones due to their advantages such as no signal shielding, resistance to falling, wear resistance, anti-folding, warm and smooth appearance, and good hand feel. Mainly used as mobile phone backplane and other mobile phone structural components.
2. Smart wearable field
Compared with metal, zirconia ceramics have better wear resistance, smooth surface, good texture, and no oxidation. Famous Swiss brands such as Radar, Apple and Chanel have launched high-end ceramic watches.
3. Optical communication field
Currently, ceramic ferrules and sleeves are widely used in fiber optic connectors. Ceramic ferrules made of high-strength, high-toughness ceramics not only meet high-precision requirements, but also have a long service life and extremely low insertion loss and return loss.
4. Biomedical field
Zirconia ceramic materials are widely used in the biomedical field as dental restorative materials and surgical tools due to their high strength, high toughness, corrosion resistance, wear resistance and good biocompatibility.
5. Automobile field
Zirconia ceramics have a small thermal conductivity and a relatively large thermal expansion coefficient, so the components used to make engine combustion chambers have good thermal insulation properties and are close to metal materials in terms of thermal expansion. It can be used as cylinder head bottom plate, cylinder liner, piston top, valve seat ring, etc. However, due toThe engine operating conditions are harsh and the strength of ceramic components changes greatly at high temperatures, so it is still some way off from commercial application.
6. Jewelry field
High-precision ceramic and precious metal alloy powders are mixed and fired, polished through several precise and rigorous processes and multiple machines, and finally integrated into jewelry designs. This kind of ceramic is not only lightweight and wear-resistant, but also anti-allergic and comfortable to wear. It is one of the most fashionable jewelry materials currently and is favored by major jewelry brands.
Many luxury brands such as Bulgari’s classic series B.Zero1 and Save The Children series, Chanel Ultra series, Cartier and other jewelry have used ceramic materials.
7. Daily life areas
Ceramics are the cultural heritage of China for thousands of years. In addition to the above-mentioned applications, ceramics are also ubiquitous in our daily lives. Ceramics have the characteristics of high temperature resistance, corrosion resistance, antioxidant, high strength, wear resistance and natural antibacterial properties, and can be used as bowls, spoons, vases, ceramic knives, etc.
